What MORE FLAWED performance?! You make it sound like she had 2 falls and a step out in her program. FYI Having unclear edges in jumps doesn't affect PCS.There has yet to be anyone able to answer why Shcherbakova deserved far higher PCS than Trusova for a more flawed performance, especially regarding the skating skills and choreography.
Sasha faced Anna 3 times last year (GPF, Nationals, European) and at all of those competitions Anna was at least 4 points ahead of Sasha in PCS (in the free skate).
What are the chances that judges at 3 different competitions put Anna far ahead of Sasha in pcs?! Maybe Anna IS actually better in PCS? Or do you believe her parents were traveling around the globe bribing judges at different competitions?!
